Application filed February 3, 1908. Serial No. 413,928.

To all'who'm it may concern:

Be it knownthat I, ARTHUR J. MORGAN,

citizen of the United States, residing at.

descent electric lamps. The chief objects of myinvention are to provide a simple, convenient, and eflicient appliance for retalning shades in position upon electric lamps; and to furnish a holder adapted to be applied to the lamp sockets in common use.

Further object of, my improvements are to provide a holder that can be quickly attached to any socket, and as readily removed therefrom; to furnish clamping means so designed as to utilize constructive elements of the socket tov aid in retaining the appliance,

and to supply means whereby the shade may be removed and replaced without disturbing the clamped connection between the device andthe socket.

I accomplish the desired results by the appliance illustrated in the accompanying drawing which forms a part of this application and which consists, in general, of an openframe work or cage, adapted to inclose and clamp the outer surface of a base or socket of an incandescent lamp of usual form, means for securing the frame in position, and retainin lugs for the shade.

.Aholder embo ying my improvements is shown in the following views.- Figure 1 is [a side elevation of an electric lamp showing method of securing a shade thereto by means of my improved shade holder; Fig. 2 is aside elevation of a socket with a holder attached; Fig. 3 is a top elevation of the holder, and Fig. 4 1s a side elevation of one section of the holder looking from the inside.

'Referring to the details of the drawing the reference numeral 5 indicates an ordinary lamp socket such as is common use in electric lighting systems.

6 is the tube or stem through which the conductors are led to the socket, and 7 the tively thin metal and is formed in duplicate sections each forming one half the said framework, which is constructed in the following manne'r;

A band or collar 10, adapted to engage the tube or stem 6, is composed oftwo semicircular parts 11, each furnished with lat-- eral flanges 12, having holes 13, said parts 11 being securely clamped together when assembled, by screws 14, one of' the holes in said flanges in .each part being threaded to ,engage the screw. From this collarlO, arms 15, bent to conform to the curves of the outer surface of the 'socketj5, pass forward to a suitable distance where they are joined together by a band or ring 16, the ends of the arms being provided with straight portions 17 adapted to engage the surface ofsaidband 16, to which they are securedby rivets 1 8, or in any other sui.able manner. The extremities of the arms are projected beyond the band 16 to form retainin 19 adapted to engage the annular ange 20 with which sha es are usually supplied. The band is made up of two pieces each extending a semicircumference as in the case of the collar 10, and are provided with analogous flanges 21, joined together by screws 14, tocomplete the structure when assem bled uponthe socket. merce the shell or casing is usually secured to the base by screws 22, furnished with round heads which project to an appreciable this feature of the ordinary fixture construction to. aid in retaining the holder in situ upon the lamp, by forming hemispherical bosses '23 upon the flat arms 15. These bosses are formedby swaging or stamping and the'under surface presents a concavity in which is received the head of the screw 22. By this arrangement the fixed heads of the screws prevent both rotary and longitudinal movements of the framework and aid materially in retaining the device in place. The collar 10 is also provided with holes 24 to permit the passage of the set screws 25 used to secure the socket to the conducting tube 6. Although only one set screw is employed, several holes 24 are furnished at spaced intervals to permit of latitude in the placing of the holder, and altliou h usually only two of the screws 22 are attac ed to a single socket each arm is supplied with a recess for the same reason as fingers In the socket of comgiven in the case of the holes, thus permitposite sides thereof, with the collar '10 emracing the tube 6 near its connection with the socket base, one of the holes 24: engaging the set screw 25 and the screw heads 22 properly covered by the bosses, the screws 14 m the collar are then set. The shade 8 is now placed within the grasp of the fingers 19 and the screws 14 in the band 16 are tightened thuscompletely securing the parts in place, i It will be seen that the resiliency of the fiat arms 15 will permit the shade to be removed or replaced by releasing the screws in'the band alone without disturbing 'the collar.-

' Having thus described my invention-what I claim as new and desire to secure by Letters Patent, is: v

i 1, A-'shade-holder forlamps, comprising an inner and an outer collar, resilient arms connecting, said collars, said arms adapted to frictionally embrace a lamp socket, .and also ada ted to engage a lamp shade.

' 20A amp socket andshade holder comprising two collars formed in sections and apart, means for connecting the members of each collar, resilient-arms connectingsaid collars, said arms having their free ends bent to embrace the lamp shade.

3. A shade holder adapted to be applied .to alamp socket, said holder comprising a frame made in separable sections the members of the frame provided with apertures and recesses adapted to engage projections upon the socket, means for clamp ng said sections together, and means for engaging a lamp shade.

4. A'shade holder adapted to be applied socket, acseries of arms attached to the collar, and furnished with recesses adapted to engage projections upon the socket, a band 7 connecting the ends of said arms,said, band being formed in sections,.means for clamping the said holder upon a socket, and'fin gers adapted to engage a shade.

5. Ashade holder for electric-lamps comosed of an inner and outer collar, each ormed of semi-circular members separably connected, arms connecting the said collars together, said arms adapted to frictionally embrace the lamp: socket substantially in the manner and for the purpose set forth.

. 6. A shade holder for electric lamps, composed of two complementary sections, each section consisting of a. semi-circular inner collar, a semi-circular outer collar, and arms connecting the corresponding inner and outer col portions together, and means for detachably connecting said complementary sections together.

-7. In combinatiouwlth an electric "lamp socket, having bosses projecting therefrom,

a shade holder comprisin arms adapted to embrace said socket and aving recesses to receive said bosses, and an inner and an outer collar connected by said arms.

In testimony whereof I aflix my signature in the presence of two witnesses.
